摘要：
The invention is directed to a method for correcting vision in a patient by modifying the refractive index of cornea tissue. The method comprises identifying and measuring the degree of vision correction of the patient and determining the position and type of refractive structures to be written into the cornea tissue of the patient to correct the patients vision. The refractive structures are written by irradiating select regions of the cornea tissue with focused laser pulses having a wavelength from 400 nm to 900 nm and a pulse energy from 0.01 nJ to 10 nJ. The refractive structures are characterized by a positive change in refractive index in relation to non-irradiated cornea tissue of the patient.
